EVA: a hybrid cyber range

Over the recent years, cyber attacks have increased constantly. Attacks targeting sensors networks, or exploiting the growing number of networked devices, are becoming even more frequent. This has led to the need to find a way to train the teams responsible for defending computer systems in order to make them able to respond to any threats quickly. The fact that it is impossible to carry out training operations directly on corporate networks or critical infrastructure has led to the birth of Cyber Ranges, virtual or hybrid systems that allow training in safe and isolated environments. In this paper we present a model for the implementation of a Hybrid Cyber-Range (HCR), based on the model of a real Water Supply System WSS). The HCR shall combine the dynamism and flexibility of virtualised Cyber-Ranges (CR) and the realism of Cyber-Physical Systems (CPS).
